This invention relates to a collapsible stool of which the variouselements can be assembled and disassembled, and fan ob ect.

ofthe invention is to secure a knock-down stool of great strength andrigidity.

Another object isto provide "a construction that will enable anyonetovery quickly 1 assemble or disassemble the various elements of thestool. a I I I The accompariaying drawings illustrate the invention. I g,1-

Figure 1 is a perspective view of a stool constructed in accordancewiththe"provisions of this invention, a-portion of the seat cover beingbroken away." i Fig. 2 is a sectional elevation of the stool. Fig. 3 isan enlarged sectional detail of one corner of the stool. v

Fig. 4. is an enlarged sectional'detai'l of the middle portion of theseatand the post. Fig. 5 is an enlargedsectional-detail of 'a portion ofone of the legsand a portion of one of the braces engaging the same.

Fig. 6 is an enlarged sectional detail of the lower portion of the postand the middle portions of the braces, showing the connec- 7 tiontherebetween.

Fig. 7 is a plan view of the seat collapsed. Fig. 8 is a longitudinalview, partly in section, of one of the le s. V Fig. 9 is a longitudinalview of one of the I braces. I I

Fig. 10 is a longitudinal view of the inner post member. Fig. 11 isalongitudinal view of the outer post member.

There is provided a seat other at'their ends as indicated at 14. Pivotedat 15 to the opposite side members 13' The pivots 14 project asubstantial dist ance below the under faces of the members zen of theUnited States, residing at Los- 12 comprising four side members 13pivoted to one an- '13 and, when the seat parts are in position to forma rectangle, the pivots 1 1 .are adapt ed to be received in the tubular11131361 ends of legs '18 which are preferably curved to a slight extentattheir lower ends as indicated at 19 .j I I l The inner sides of thelegs 18are provided with slots 20 of suiiicient length to admit theinsertion into the slots of the ends of braces 21. There are two braces21- and said braces are arranged diagonally relative to the rectangularseat 12 and each brace is adapted to engage} diagonally opposite legs18. In order to I prevent spreading apart of the legs 18, the braces 21are provided near their ends with notches22 in their upper edges so asto hook beneath the upper edges of the slots 20. I e

h The braces 21' are formed of strip spring metal and are shaped so thatthe middle portions thereof lieat a rightangle to the endportions tomake the middle-portions parallel with the seat members 16 which mayalso be of strip metal Thebraces 21 areprovided centrally withperforations28; The pivot 17 constitutes a tie rod as it is suflicientlylongto extend from the seat 12 through the perforations23 and projectbeneath the crossed braces 21. The pivot 17 passes loosely throughperforations 171 in the seat members 16 and is provided with a head 172to seat against the upper face of the uppermost seat member 16. Thepivot 17 is screw-threaded at its lower end, as indicated at 24, toreceive a wing nut 25 which bears againstv the under brace 21 so as, toforce the braces upwardly to hold them with their notches 22 hookedsecurely into the legs 18 and to hold the legs and seat assembled.

Means are provided to limit upward motion of the middle portions of thebraces 21 so that the legs 18 will not be bent inwardly I of the upperbrace 21. The member 26 is a preferably ofv such length that, when theWingnut 25 is tightened to holdthe seat and bracestoward one another,said braces will be slightly sprung or bowed v upwardly at their middleportions so as-to be under tension. This tension tends to preventthebraces from disengaging the legs 18.

- If desired, the seat 12 maybe provide'c't with a. suitable fabriccover comprising-atop 5 jecting end of the pivot 17 andthestraight endsof the legs 18 will be slipped over-the pivots 14. Then the braces 21will ;be;pla( :ed with, their perforations 23 engaging the projectingend of the pivot17and with their notches 22engaging the legs 18; Thenthe Wing nut 25 Will be; applied to .the post member 17 a-nd'tightenedto slightly bow-the braces upwardly and securely clamp them to the legs.

The stool will then be turned into upright position. If it be desired'toruse the-pseat cover-27, said cover may he slipped over the seat 12.;When the, foregoing operations have been completed --.the parts will be;as;

sembled'as shown in Fig. 1; l-\-reversal of the. abovedescribedoperations will place the parts in the knock-down condition.
